you are probably better off getting some square or rectangle high strength steel tube and having them fashioned to match original rails. Likely would be stronger, faster and less expensive. Very unlikely to find good used and not sure if BMW ever made replacements ... check realoem.com
Our machine shop welder has made before could make again

you are better off just finding a plug for a later model flasher box and flasher switch as even if you find one likely to have issues ?
good luck... we recently just pulled plug and flasher box from 320i for a 70 build... .worked great

Sounds like your fuel pressure or cold start are dumping to much fuel and have flooded the plugs
Unfortunately with Tii's once plugs are flooded they are very slow to dry out. Best to pull them clean or better yet just replace with some new. To find out if to much fuel take a small towel and a vice grip and squeeze off the line to KF pump. You can partly cut it off or fully cut off. Then crank... the residual fuel in system will likely make it run a second. All fixed then release vice grip on line.
Now adjust your pump for correct fuel setings and / or adjust cold start
Now check your cold start to see if coming or or not or possibly staying on
I know purist love to keep the cold start auto timed relay but we almost always disconnect relay and run a normal off button to left of steering wheel. When held in lets cold start have fuel when released no fuel. Or sometimes will connect to starter so automatically runs just when cranking engine
Both approaches are superior to depending on expensive fragile cold start relay
For security I always suggest to new Tii owner keep spark plug wrench and fresh set of plugs in trunk. Easy fix if get flooded to get home then do final corrections
Obviously before doiing all this check for spark but you post said you had spark ?
Good luck KF inject cool technology but when it goes bad will remind you of best Rube Goldberg experiment :)

we manufacturer our own brackets. We can tune it a bit to early model or late model cars. Designed to work on early model cars without the high bolt mounts on block and to work on later model cars with the high bolt mounts the Hobie Dave bracket requires
Also have new tensioners and pulleys as works better with pulley and tensioner
